Rear Extension & Loft Conversion – Shepperton, Surrey
This Shepperton home has been completely transformed with a large rear extension and loft conversion, creating a modern, open-plan living space designed for comfort, style, and functionality. The homeowners wanted to expand their ground floor to accommodate a spacious kitchen-diner and living area, while the loft conversion added valuable extra space upstairs.
To make this possible, PorthouseDean provided expert structural calculations, ensuring all elements were safe, structurally sound, and fully compliant with Building Control.
Creating a Bright & Spacious Home
The project focused on:
✅ A large open-plan kitchen & living space – Designed for modern family living
✅ Bi-fold doors opening onto the garden – Seamless indoor-outdoor connection
✅ A loft conversion for extra space – Maximising the property’s potential
✅ Structural steelwork & RSJs – Supporting wide openings and open-plan design
Precision Engineering for a Seamless Build
Our role in this transformation included:
✔ Structural calculations for the rear extension & loft conversion – Ensuring full stability
✔ Steel beam (RSJ) design – Supporting the large glazing and open-plan layout
✔ Load-bearing wall assessments – Creating a safe and well-integrated structure
✔ Foundation design – Ensuring the extension was built on a solid base
With these calculations in place, the homeowners now enjoy a bright, modern, and beautifully designed living space that enhances both comfort and functionality.
